WERNER 'lI-IRIG, OF ZURICH, SWITZERLAND.

SAFE.

Application filed October 16, 1919.

To all whom t may concern Be it known that I, VERNER THRIG, a citizen of the Republic of Switzerland, and resident of 7 9 Asylstrasse, Zurich, Switzerland, have invented certain new and useful Improvements in Safes, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to reinforced or armored concrete safes.

The present invention provides a safe in which the body and also the door each consists of a single monolithic concrete body l5 which is formed in one casting, and the arrangement of the reinforcement by the interlacing of the metal bars which are situated substantially throughout the concrete is such as to enhance the elasticity while securing 2O burglar-proof qualities.

The new arrangement not only enables rapid construction at a minimum of cost, iron and steel being largely dispensed with, but as a result of practical tests it is claimed that in the matter of resistance to fire and burglary the improved safe has considerable and far reaching advantages over previously known constructions of safes.

The invention is illustrated by way of example in the accompanying drawings in which Figure 1 shows a front view of the safe.

Fig. 2 shows a vertical section thereof.

Fig. 3 illustrates a sectional plan of the Safe.

' Fig. 4 shows a detail of the construction,

and

Fig. 5 a modification of same.

Fig. 6 is a detail perspective view of the 40 rods and bars interlaced in screw-like manner.

In the drawing a is the body of the safe which is formed in one piece, and b is the door, which is also in one piece, both body and door being made of armored concrete.

The safe is constructed in the following manner In forming the body and the door of the safe respectively, a framework comprising outer and inner casings and which can be easily taken to pieces is provided. The framework is made of wood, iron or such like material and is not shown on the drawing. Between the outer and inner casings the armor c and d is inserted, carebeing taken to keep the -armorat a sufficient dis- Specicaton of Letters Patent.

tance from the walls of the framework. Concrete reinforced with other materials enumerated further on, and which render it capable of exceptional resistance when it has set and hardened, is poured in so as to completely fill up all the remaining space, the armor being thus surrounded and held fast on all sides. Vhen the concrete has hardened the frame work is removed and may be employed again for the construction of other safes.

To render the concrete particularly hard and resistant a percentage of reinforcing material is mixed therewith, such for example as metal filings or metal dust, glass dust or residues of burnt thermit, or silica, fibers of asbestos, powdered zinc, zinc oxid or similar substances.

The armor reinforcing the body a and the 75 door Z) of the safe is disposed in an improved manner, the iron or steel bars being interlaced into regular or irregular polygonal or star-shaped forms d, and winding in screw like manner around iron or steel rods c which form part of the armor. This form of reinforcement enhances the elasticity and burglar-proof qualities of the safe. Any attempt at burglary by means of hammer and chisel or similar tools is attended with great difficulty as the tool employed encounters and is arrested by the armor. The reinforcement described also defies any cutting implement, as each rod would have to be freed from the adhering mass of concrete before the cutting implement could get to work, and it would thereupon encounter the twisted bars running across and interlacing the rods.

To further strengthen the door b horizontal and vertical metal tubes e are added to the armor, the tubes e being filled with resistznt material such as concrete or hardened stee The armor may if desired be disposed in the shape of trestle-work and steel or iron spirals. The lock f together with its bolts g is mounted on the plate L embedded in the concrete on the inner side of the door and is thereby kept out of contact with the concrete. Any examination of the lock and any repairs that may become necessary are thus facilitated, and furthermore the strength of the door is in no way lessened.

To prevent dust entering and to impart a neat finish a removable metal plate i surmounts the lock and its component parts on the inside of the door. The bolts are adapted to shoot into metal sockets embedded in concrete which form one piece with a concrete embedded metal frame s disposed right along the inside of the door. If desired, the lock and its component parts could be embedded in the door, but this would tend to weaken the door and would lessen its resistance to burglary.

The door is pivoted on a shaft 7c incased in armored concrete. The shaft la, which incidentally serves to strengthen the armor of the door is engaged at each end by a bolt or pin l, each of these bolts being fitted in a sleeve Both sleeves are embedded in the body a of the safe, and are formed in one piece by being riveted or otherwise secured to an iron frame fn, located on the inside of the body a of the safe. The iron frame n. is joined by means of small intertwined reinforcements (see Fig. 3) to the metal frame s that surrounds the frame c' of the lock. By thus placing the accessories of the door on the inside, the safe is kept free from all exterior protuberances that4 might prove suggestive in an attempt of burglary.

It will be understood however that the door of this safe could be supported in known fashion,- in so-called socket hinges.

At the top and bottom and along the side opposite to that at which it is hinged, the door b is provided with a grooved metal border o which when the door is closed fits into a corresponding grooved border p on the frame n. By this means, a closure is formed between the body of the safe and the door which prevents fire, smoke-gases, etc., penetrating to the interior of the safe. The groove could alsoinstead of being adapted to the outside of the safe, be placed inside as shown in Fig. 5, in which on the side wall to the left of the body of the safe, and inside the door, two grooved metal borders a and Q-one fitting into the other are shown, the metal borders being welded or riveted to the metal frame on the inner side of the door. The borders can of course, if desired be formed differently to those illustrated.

In the safe herein described, which is completely fire-proof all valuables can be safely stored.

lVhat I claim and desire to secure by Letters Patent is:

l. A safe comprising a body portion formed of concrete, rods in said concrete, bars in said concrete, said rods and ybars being interlaced in screw-like manner, and a door, said rods and bars being situated substantially through the concrete.

2. A safe comprising a body portion formed of concrete, rods in said concrete, bars in said concrete, said rods and bars being interlaced in screw-like manner, a door formed of concrete, rods in said concrete, and bars in said concrete, said rods and bars being interlaced in screw-like manner, and situated substantially throughout the concrete.

3. A safe comprising a body portion formed of concrete, armor therein consisting of interlaced rods and bars situated substantially throughout the concrete, a shaft inclosed in said armored concrete, and a door on said shaft, said door being also formed of armored concrete.

ln Witness whereof I have hereunto set my hand in presenceof a witness.
